Abstract

The invention provides a vehicle operation simulation calculation system based on real-time acquisition of driving operation data. The input end of the vehicle operation simulation calculation systemis connected with a driving simulator Logitech G29; the vehicle operation simulation calculation system comprises a real-time data acquisition and storing subsystem, a vehicle dynamics real-time calculating subsystem, a system simulation logic control subsystem, and a vehicle operating parameter dynamic output subsystem; and an 100km/h to 0km/h emergency braking comparison experiment is obtained by comparing the vehicle operation simulation calculation system with a CarSim vehicle simulation system with the same vehicle basis attribute parameters, the relative errors of the braking time and abraking distance obtained by the vehicle operation simulation calculation system are 5.065%and 8.314% correspondingly, results obtained by the vehicle operation simulation calculation system and the CarSim vehicle simulation system are highly consistent, and the expected functional requirements can be met.

Description

technical field [0001] The invention belongs to the field of vehicles and road traffic safety, relates to a vehicle running simulation system, in particular to a simulated vehicle running calculation system based on real-time collection of driving operation data. Background technique [0002] The real-time acquisition technology of driving operation data and the real-time simulation technology of vehicle dynamics are the basis of real-time performance, high efficiency and accuracy of vehicle operation simulation system simulation. The vehicle operation simulation system based on real-time operation data collection has been widely used in various driving simulators such as driving training, new model development, and road traffic safety simulation at this stage. [0003] At present, most of the data acquisition cards used by manufacturers are aimed at signal data acquisition in a single aspect. Few companies can provide data acquisition cards that combine software and hardwar...
